In the crawl there is R-19 Kraft faced fiberglass batts stuffed in between the floor joists with wire supports. The facing is toward the living space, that is when Im in the crawl space and look up, I see pink fiberglass in between the joists. In some areas the pink fiberglass is stringing out in a cobweb fashion. My home inspector told me it is from the weight of moisture.

1) In many spots the wire supports have compressed the insulation. I have a mind to loosen them. Will the insulation decompress naturally?

2) Is this the correct install? The crawl floor is lined with plastic and there are some moisture under this plastic. Also it is always humid in the crawl and my HVAC evap blower sweat in the summer down there. I would almost think the insulation vapor barrier should be installed kraft away from the living space here. This is how my fathers home is. Why have kraft faced insulation here at all, why not unfaced?

When the warm, moist air from your home tries to escape, it is stopped at the vapor barrier. If the barrier is on the heated side, it stops here as a vapor. If it continues through the insulation to the vapor barrier (installed backward) it condenses to water and soaks the insulation.
